Question

the area of a square field is 60025 square A man runs along its boundary at 18 km per hour in how much time will he returned to the starting point​

Answer 1

Answer:

Area=60025 m square =side^2

Therefore, side of field= 245m

Now, the perimeter or the length of boundary of field= 4*side= 980m

Now, we know that speed=distance/time

But given speed is in km/hr

So, speed in m/s= 18*(1000/3600) =18*(5/18) = 5m/s

Now, speed = distance/ time

So, 5= 980/t

So, time taken= 980/5= 196 seconds

or 3 minutes 16 seconds.

Answer 2

Step-by-step explanation:

area of square=s^2

60025=s^2

s=√60025

s=245

sorry but it's not given 60025 is sq.m or sq.km

perimeter=4s

=4×245

=980m (Or km)

most probably it's km

time taken=980km/18

=54.444hrs

or if m 980m

then time=0.0544hrs
